In general, reinforced concrete (RC) structures frequently experience performance degradation due to corrosion, primarily when rebar in concrete is exposed to chloride, either from the concrete ingredients or from external sources. Furthermore, the suitability of RC structures can be greatly impacted by high temperatures or fire exposure, which can alter the material properties of RC structures and result in the loss of bond performance between the rebar and concrete. Therefore, this study assessed the bond strength between corroded steel bars and concrete by considering the effect of different temperatures. The specimens were corroded using an accelerated corrosion method to corrode the reinforcement bars embedded in concrete specimens. The specimens with corroded steel bars and without corroded steel bars were placed in an oven and exposed to different temperatures (0 ℃, 250 ℃, and 500 ℃). The specimens were heated in an oven at predetermined temperatures (0 ℃, 250 ℃, and 500 ℃). Finally, pull-out tests were performed to determine the ultimate bond strength for each specimen. Furthermore, this study investigates the failure mode of the specimens after exposure to high temperatures at various corrosion levels. In summary, both corrosion levels and temperature exposure significantly influence the bond strength between steel and concrete. The results indicate that the bond performance of the concrete and steel bars is affected by the corrosion level of the steel bars and the exposure temperature.
